SPECIFICATION forming part of Letters Patent N 0. 686,336, dated November 12, 1901.

Application filed January 21, 1901. Serial No. 43,969. (No model.)

To ctZZ whom it may concern.-

Be it known that I, GEORGE F. READ, a citizen of the United States,residing at New York, countyof Kings, and State of New York, have invented certain new and useful Improvements in Paste-Fountains for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in devices for applying to moving material, such as a web or sheet of paper, liquid-such, for instance, aspaste-in a transverse line or lines.

Transverse pasting devices now ordinarily used in the art, and more particularly those used in connection with fast rotary printingmaohines, employ a rotating blade to which paste is applied, the blade in turn transfer ring the paste in a line to the moving web of material. The movement of such pastingblades is necessarily rapid,and there is always liability that the paste will be thrown or flirted off the blade onto the material. Furthermore, the transverse pasters now ordinarily employed are complicated and expensive in construction.

. The object of this invention is to produce a simple, compact, cheap, and efficient device which may be used for applying transverse lines of paste orothersimilar substances to moving material, such as a web or sheet of paper, and which avoids the objection heretofore stated.

With this and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combiplication of the improved pasting device to a printing-machine.

Referring to the drawings, which illustrate a concrete embodiment of the invention, 1 indicates a portion of a frame of a printing or other analogous machine in which is supported a moving liquid-receptacle 2. In the preferred form of the construction this receptacle will consist of a rotatingfountain.

Any suitable means may be employed to support the fountain in the machine so that it may be given a rotating movement, and the fountain Will preferably be so arranged in the machine as to be detachable from its support. In the preferred form of the construction the support for the fountain consists of heads 3 and 4,the head 3 being suitablysecured to a short shaft 5 and the head 4 being similarly secured to a short shaft 6. These heads are or may be connected by webs 7, as shown in Fig. 3, the webs being spaced apart so as to allow the fountain to be placed between them. 'Each end of the fountain is preferably provided with a forked bracket 8, en-

gaged by a screw 9, tapped into the head. With this construction it will be seen that the fountain may be readily removed from the supporting-heads, and any desired adjustmentof the fountain with respect to the heads may be secured. One of the short shafts, herein shown as the shaft 6, is provided with a gear 10, so that the shaft may be driven from any suitable rotating part of the machine.

The fountain is provided with a suitable applying device which may be varied widely in form and construction. In the preferred form of the construction this applying device will not only move with the fountain, but be given an independent movement with respect thereto. In the construction shown the applying device consists of a roll 11, preferably provided with a groove 12, for a purpose to be hereinafter stated. This roll 11 is mounted in a long bearing, preferably formed integral with the fountain, an aperture 13 be- 5 the aperture 13 opens into this pocket. The centrifugal force developed by the rapid rotation of the fountain will tend to hold the paste or other liquid in the pocket, so as to insure an adequate amount being supplied to the roll. The bearing for the roll is so formed that the roll fits snugly therein. The edges of the aperture 13 therefore serve as a cleaning device for the roll and act to scrape from it all the liquid except that which is contained in the groove 12.

Any suitable means may be employed to give the roll the independent rotation it has with respect to the fountain. As shown, a gear 15 is provided,-which is formed integral with the bushing 16, through which the shaft 6 passes, the bushing being made stationary with respect to the frame by means of a screw 17 or in any other suitable manner. The gear 15 is engaged by a pinion 18, secured to a short shaft 19, which is shown as mounted in the head 4. The inner end of this short shaft 19 is provided with a grooved head 20, which is engaged by a sliding clutch-piece 2l, suitably secured to the roll 11. This clutchpiece is slidingly secured to the roll and is held in position by means of a bolt 22 or in any other suitable manner. Inasmuch as the gear l5'is a stationary gear it will be seen that as the fountain rotates the pinion 18 will be carried around onto the gear 15 and the roll 11 will be given its rotation.

Suitable means are provided which cooperate with the roll 11 to force the material to be pasted against it. In the construction shown these means'consist of a blade 23, secured by screws 24 or in any other suitable manner to a cylinder 2-5. This cylinder is preferably formed with shafts 26 27, extending into suitable bearings in the frame. Any suitable means may be employed for rotating the cylinder 25. As shown, however, the head 3 has connected to it, by means of screws or in any other suitable manner, a gear 28, meshing with a gear 29, mounted on the shaft 26. WVhile the gears 28 and 29 might be made of the same size, so as to cause the blade to cooperate with the roll 11 in the fountain on each revolution of the fountain and blade-carrying cylinder, this would under some circumstances necessitate making the fountain and the blade-carrying cylinder of a large diameter, since it is usually desired to place only a single transverse line of paste on each sheet or each section of web which is to form a sheet. In order to reduce the size of the fountain and the bladecarrying cylinder, therefore, each of these devices is given a predetermined number of revolutions with reference to the length of the sheet or the section of web which is to form the sheet, the number of revolutions of the fountain being diiferent from that of the blade-carrying cylinder, the arrangement of the gearing being such that the blade will meet the paste-applying roll after the fountain and the blade-carrying cylinder have made the predetermined number of revolutions. The predetermined number of revolutions given to the fountain and the bladecarrying cylinder may be varied as required by the special circumstances of each case. In the construction shown the fountain is arranged to be given two revolutions for each passing sheet, and the relation of the gears 28 and 29 is such that the cylinder makes three revolutions while the fountain makes two. On everysecond revolution of the fountain, therefore, and on every third revolution of the cylinder 25 the blade 23 will force the passing web or sheet into the groove in the roll 11 and cause a transverse line of paste to be applied to it.

In order to insure that the roll 11 is positively held in its bearings, collars 30 are provided at each end of the roll, these collars being secured to the roll in any suitable manner. In order to permit these collars to pass the cylinder 25, said cylinder is provided with suitable recesses 31.

The operation of the construction will be evident from the diagram, Fig. 4c. In this figure, 32 and 33 indicate the form-cylinders of a perfecting printing-machine. After the web is perfected it is slit by means of slitters 34. One part of the web is then carried through a suitable transferring mechanism 35 over a guide 36 and between rolls 37. The other part of the web is led over a guide 38 and then between the fountain 2 and the blade-carrying cylinder 25, (said parts being diagrammatically illustrated in this figure.) As the web passes through this pasting device it receives a transverse line of paste and is then led between the rolls 37, by which it is caused to adhere to the first part of the web. The two parts of the web thus secured together pass between the cylinders 38 of an ordinary cutting, collecting, and folding mechanism, and after being cut into sheets and suitably folded are delivered to a fiy 4:0 or to any other suitable delivery mechanism. In this figure the fountain 2 is shown as being operated by a train of gears 41 from the cutting and collecting cylinders.

While the device which has been described is particularly applicable to the application of paste or other similar adhesive substance, and it is to be understood that the word paste is used in a generic sense in this specification to include any form of adhesive substance, it is obvious that the construction could be used for applying any other liquid which is generally similar in character.

While, further, the construction which has been described herein is particularly efiective for the purpose, it is to be understood that the invention may be embodied in other constructions which are widely different from the one described. The invention is not, therefore, to be limited to the precise details of construction herein set forth.
